Which disease is caused by bacteria?

Tuberculosis Malaria Ringworm Polio

Correct Answer:

Tuberculosis

Explanation:

Bacteria are single-celled organisms that can cause infections. Tuberculosis is caused by a bacterium, Mycobacterium tuberculosis, so it is a bacterial disease. Malaria is caused by a parasite (Plasmodium) transmitted by mosquitoes. Ringworm is a fungal infection caused by dermatophyte fungi. Polio is caused by a virus. Recognizing the type of organism behind a disease helps explain why certain treatments work (antibiotics for bacteria, antivirals or vaccines for viruses, antifungals for fungi, antiparasitics for parasites).
